My real question is...
If I'm

If I'm wanting to start a new ecommerce site NOW and not familiar with Drupal 7 yet, which platform do I move towards? I have already set up an extensive demo site for the new site concept on UC 2.x. There are many modules which won't be ported and possibly not included in UC 3.x for Drupal 7. And Drupal Commerce is not near ready to build on for production. I don't want to end up 'painting myself into a corner' so-to-speak with a system that is no longer maturing.
